Title: Improvements in or relating to motor circuits and switches therefor
Inventor: CURTIS THOMAS JOSEPH
IPC: H01H35/10
Filed: 1965-02-17
Abstract: 1,081,372. Control of A.C. motors; speed responsive switches. GENERAL ELECTRIC CO. Ltd. Feb. 16, 1966 [Feb. 17, 1965], No. 6843/65. Headings H2B and H2J. A split-phase motor driving a waste disposal unit alternates its direction of rotation on successive energizations of the motor circuit to prevent the build-up of waste upon the blades of the unit. A centrifugal switch is connected in series with the starting winding of the motor and is closed when a main switch is opened to stop the motor. Such operation of the centrifugal switch causes the contacts of a reversing switch to be changed over so that the motor accelerates in the opposite direction when it is restarted. The centrifugal switch engages arm 34 when the motor is switched off, to rotate shaft 27 and hexagonal indexing member 24, which are then locked together, until projection 38 engages an end of a slot in bracket 32. This rotation of the member 24 urges blades 14, 15 of the reversing switch outwardly from board 11 until an apex of the hexagonal profile energizes grooves 19, whereby contacts 16 engage the other fixed contacts of the reversing switch. The member 34 is then freed from the centrifugal switch so that it and shaft 27 are returned to their original positions by spring 35, leaving member 24 in its indexed position. Contacts 16 are thus moved alternately between the two operative positions of the reversing switch. In a modification the motor is of the three-phase type.

Title: An improved reeling device for wire and the like
IPC: B21C47/04
Filed: 1931-03-07
Abstract: 374,430. Winding wire &c. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Larsen, E. W. ; 2048, Cleveland Avenue, Chicago, U.S.A.) March 7, 1931, No. 7160. Convention date, March 7, 1930. [Class 120 (ii).] Apparatus for winding wire &c. comprises an arbor driven by a rotatable sleeve, a slidable shaft extending axially from the arbor and the sleeve and means controlled by the movement of the shaft to lock a reel or drum. A housing 18, Fig. 1, supports a stationary sleeve 22 which projects some distance therefrom and encloses a rotary sleeve 30 driven by a drum 75. Adjacent the housing, the stationary sleeve is formed with a shoulder 23, Fig. 3, against which a ball bearing 24 is located to support a rotary barrel 63 secured at its outer end to an annular member 31 mounted on the outer end of the rotary sleeve 30. An endplate 54 secured to the inner end of the barrel carries pivoted latches 58 having lips 60' to engage the under surface of a drum 51 and projections 59 to engage slots in the drumhead 62 to compel the drum to rotate with the barrel. The annular member 31 is formed with three pairs of abutments 32 between each pair of which is pivoted a right-angled finger 34 having at its outer end a pivoted latch 36 comprising a shoulder 46 adapted to engage a head 47 of the drum or bobbin 51 and a lip 50 which engages the undersurface thereof. The annular member 31 is secured to a cap 41 having slots, in which the fingers 34 are disposed, and a central aperture 43 adapted to receive a conical cam member 45 against which rollers 35 on the fingers 34 are pressed by springs 39 disposed between the fingers to draw them inwards. The cam member 45 is carried by a rod 69 disposed in and keyed to the sleeve 30, the rod extending beyond the drum 75 to a clutch 79 which connects it to a spring-loaded piston 83 pressed towards the further end of a cylinder 81. When a drum has been filled, fluid pressure is applied to the piston 83 to overcome the spring pressure and force it outwards, the cam member 45 being thereby displaced outwards to permit the springs 39 to draw down the fingers 34 and remove the latches 36 from the path of the drum as it is ejected from the arbor comprised by the cap 41, annular member 31 and barrel 63. To effect the ejection, a slide bar, in the base of the device, formed on one side with rack teeth is moved forward by pinions driven by an air motor to engage the head 62 and push the drum partly off the arbor. The bar is then retracted, the drum removed and a fresh drum engaged with the latches 58. On freeing the piston 83 from the applied fluid pressure, the cam 45 is moved to thrust outwards the fingers 34 and bring the latches 36 into engagement with the drumhead 47, the arrangement being self-centring.

Filed: 1946-03-11
Abstract: 609,524. Multiplex radio signalling; valve generating circuits. FAUDELL, C. L. March 11, 1946, No. 7460. [Classes 40 (v) and 40 (vi)] In a superheterodyne receiver for two carriers, one of which is modulated by vision and synchronizing signals and the other by sound signals, a single I.F. channel 5, Fig. 1, is provided and the local oscillator 1 produces the appropriate I.F. from the vision and synchronizing carrier except during the synchronizing intervals when its frequency is changed by pulses from the line scanning generator 11 over lead 13 to produce the same I.F. from the sound carrier. The sound reproducer 9, 10 is disabled during the receipt of vision signals, but released by pulses over lead 14, which may also black out the vision reproducer 7, 8 over lead 15, during receipt of the sound signal. A common second detector 6, coupled to the LF. amplifier 5, feeds the sound reproducer 9, 10 and vision reproducer 7, 8. In one circuit for changing the local oscillator frequency, the control pulses render conducting a diode in series with a condenser which is thus connected across the frequency determining circuit, Fig. 2 (not shown). An alternative circuit comprises a thermionic reactance which is effectively shunted across the frequency - determining circuit of the oscillator only when its valve is rendered conductive by pulses applied to its suppressor grid, Fig. 3 (not shown). In another local oscillator circuit, the cathode control grid and screen grid of a pentode valve 39, Fig. 4, are connected as a triode Hartley oscillator with tuned circuit 17, 18 and pulses 40 applied through terminal 13 to the suppressor grid overcome the anode current cut-off bias from source 41 and render condenser 37 effective to re-tune the oscillatory circuit.

Title: Improvements in or relating to the regeneration of non-aqueous solvents, such as those employed in the dry cleaning industry
IPC: D06L1/10
Filed: 1930-03-10
Abstract: Solvents, such as are used in dry-cleaning, are regenerated by treating with about 0,05 per cent of anhydrous or concentrated acid, and after separation of the flocculated material neturalizing the free acid in the purified solvent.  A used petroleum distillate is agitated with 0,05 per cent of concentrated sulphuric or phosphoric acid, or hydrochloric acid gas, and the flocculated material separated by sedimentation, centrifuging, or filtration.  The supernatant solvent is then treated with ammonia or filtered through an alkaline bed, e.g. quicklime, or caustic soda or potash, or sodium carbonate to which may be added an inert filtering agent, e.g. fuller's earth or sand.  The acid sludge formed in the first stage in the process may be treated with alkali and steam-distilled to recover solvent therefrom, or the sludge may be used to accelerate flocculation in a further batch of solvent.
